An important operational characteristic of an airport is the length of its longest runway. The longest runway determines the types of aircraft that can use the airport and dictates the operational limitations at the airport. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 54: Development of a Small Aircraft Runway Length Analysis Tool provides a user-friendly computer tool to help airport planners and designers estimate runway length requirements for a variety of aircraft and design...

Airport economic impact studies may accurately measure the activity that occurs on airport properties or is tied directly to airport operations (such as off-site parking and hotels that accommodate airline crew who overnight in a location), but they do not capture how air service supports business and employment throughout the region. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 53: Measuring and Understanding the Relationship Between Air Service and Regional Economic Development...

Command-level decision making is a critical factor in successfully managing and mitigating critical incidents. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 52: Command-Level Decision Making for Transportation Emergency Managers is a document done in collaboration with TRB's National Cooperative Highway Research Program (NCHRP) and Transit Cooperative Research Program (ACRP). The work is designed to assist public transportation agencies, state departments of transportation (DOTs),...

Federal Aviation Administration (FAA) regulations require the licensing of spaceports and launch vehicles, which includes the assessment of environmental impacts. The TRB Airport Cooperative Research Program’s ACRP Web-Only Document 51: Commercial Space Vehicle Emissions Modeling presents a user-friendly tool for practitioners to estimate the emissions associated with commercial space vehicle activity. Supplementary materials to the document include an Emissions Example Information & Users Guide , th...

In the process of reducing  sustainable alternative jet fuels ( SAJF), emissions of other pollutants may also be reduced, which could be significantly beneficial to airports. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 35: State of the Industry Report on Air Quality Emissions from Sustainable Alternative Jet Fuels captures the current status of knowledge to reduce carbon dioxide emissions using SAJF.   These reductions are not yet well defined, leaving airports unable...

With the airport industry's introduction and early adoption of safety management systems (SMS), safety processes are taking on a more proactive way of doing the business while continuously improving safety. This shift in approach will drive safety research in the near and long-term future. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 50: Research Roadmap on Safety Issues reveals evidence of this shift, with input from the industry clearly indicating that more detailed guidance on...

The TRB Airport Cooperative Research Program's ACRP Web-Only Document 42: Toolkits and Resource Library for Airports and Unmanned Aircraft Systems provides supplemental material to Volumes 1 , 2 , and 3 of ACRP Research Report 212: Airports and Unmanned Aircraft Systems .

Knowing where people are at different times of the day potentially enables the design of airspace routes that minimize the environmental impact to a shifting population on the ground. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 48: Evaluating the Use of Spatially Precise Diurnal Population Data in Aviation Noise Studies examines the potential role of spatiotemporal population data in aviation noise studies. Aviation noise analysis has traditionally focused on modeling the noise ...

The administration and human resources functions within an airport can experience great challenges as airports grow, diversify, experience changing priorities, bring in new technologies, or change in other ways. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 49: Research Roadmap on Airport Administration & Human Resource Issues recommends priorities and timing, sets a research strategy, and provides a rationale for the research recommendations. Supplemental materials with this ...

As the frequency of commercial space operations and number of licensed launch sites in the United States continue to grow rapidly, accurately assessing the impacts of propulsion noise and sonic booms on surrounding communities will become even more critical. The TRB Airport Cooperative Research Program's ACRP Web-Only Document 47: Commercial Space Operations Noise and Sonic Boom Measurements develops a well-documented, high-fidelity database of acoustic measurements acquired using a consistent data colle...
